Abstract

The differentiation of composite resin from teeth using fluorescence emission was investigated as basic research for the visual detection of resin filled teeth in mass dental health examinations. Fluorescence spectra were taken from extracted human maxillary central incisors and 12 types of light-cured composite resins with a maximum of 15 shades via excitation using light with wavelengths of 400-500 nm. The fluorescence intensity ratio of resin to tooth was lowest around 500 nm for all the resins. The fluorescent images were taken based on spectroscopic results, which confirmed discrimination between the resin part and the tooth in the resin filled tooth.

摘要

作为大规模口腔健康检查中树脂填充牙视觉检测的基础研究，对利用荧光发射区分复合树脂和牙齿进行了调查。通过使用波长为400 - 500 nm的光激发，从拔除的人类上颌中切牙和12种光固化复合树脂（最多15种色调）获取荧光光谱。所有树脂在500 nm左右时树脂与牙齿的荧光强度比最低。基于光谱结果拍摄了荧光图像，证实了在树脂填充牙中树脂部分和牙齿之间的区分。
